Large number of changes to Finley for meshing in MPI.

- optimisation and neatening up of rectcanglular mesh generation code
- first and second order 1D, 2D and 3D rectangular meshes are now
  available in finley and escript using MPI.
- reduced meshes now generated in MPI, and interpolation to and from 
  reduced data types now supported.
